Well it's no walk in the park that's for sure.. I'm just thankful im not killing my team mates so much now... Just takes a little getting used to, awesome team work capabilities.
Usually I find it pretty easy. I'm usually not really thinking that much I just do. But some days I'll just have someone on the other team that's giving me crap or I just am not in the groove.
The difficulty depends on what class do you get.For marines personally for me difficult is playing with the average m4 one the second hand with sergant m4's its really easy to play
